  • Patent number: 8753997
    Abstract: The use of fuel cells to produce electricity are known as an environmentally clean and reliable source of energy, and show promise as an automotive power source if the polymer electrolyte membrane fuel cell can be made less expensive, more durable, reduce or eliminate humidification of the reactive gases, and operate at temperatures encountered during automotive operating conditions. The use of an electro-catalyst formed from heteropoly acids immobilized by a conductive material, such as carbon or platinum black, and stabilizing a metallic black with the immobilized conductive material addressed these automotive fuel cell needs. Coating the fuel cell electrode, polymer electrolyte assembly with a nano-particle catalyst derived from a heteropoly acid provided anodic carbon monoxide tolerance at anodic overpotentials and an active cathodic oxygen reduction. The heteropoly acids can also function as supercapacitor electrode films.

  • Patent number: 6387837
    Abstract: This invention relates to a process for the free-radical polymerization of monomers in gas phase or suspension processes using a supported, polymerization-initiating system comprising a) one or more polymerization-initiating components which initiate and start free-radical polymerization, b) a support, onto which said polymerization-initiating component is applied, and c) optionally, one or more modifiers which have an influence upon reaction kinetics and/or product properties.

  • Patent number: 6350835
    Abstract: The invention relates to aqueous emulsions of peroxyesters comprising an anti-freeze agent, a polyvinyl acetate with a degree of hydrolysis between 45 and 68%, and a non-ionic surfactant with an HLB value greater than 16 selected from alkylene oxide block-copolymers, ethoxylated fatty alcohols, and ethoxylated fatty acids. The emulsions are safe, storage stable, and generally applicable.

  • Patent number: 6348429
    Abstract: Cement compositions including initiation systems containing at least one peroxide or amine which has a higher molecular weight than the heretofore-employed peroxide BPO and amine DMpT, respectively. In particular, derivatives of peroxides and amines bearing large substituents relative to BPO and DMpT and polymeric peroxides and amines are suitably employed in the reaction mixture. Through the use of these initiator systems in which one or more of the components has reduced mobility relative to the materials employed in the conventional mixtures, it is possible to control the exothermicity and the peak temperature of the polymerization, while nonetheless achieving timely and adequate polymerization of the material. Concurrently, the choice of components for use in the initiation system advantageously results in a reduction in the generation of waste products and in the potential toxicity of the composition.

  • Patent number: 6323378
    Abstract: A method and composition are disclosed for the oxidation of aromatic substrates in the presence of oxygen, a catalyst, a proton source, and a non-gaseous reductant. In a preferred embodiment, benzene is oxidized to phenol in the presence of oxygen, a vanadyl catalyst, trifluoroacetic acid as a proton source, and ferrocene as a reductant. The method is economical, safe, and amenable to commercial scale-up.

  • Publication number: 20010023282
    Abstract: A catalyst composition comprising (a) an iron-containing compound, (b) an organomagnesium compound and (c) a dihydrocarbyl hydrogen phosphite is disclosed for polymerizing 1,3-butadiene into syndiotactic 1,2-polybutadiene. The use of the catalyst composition of this disclosure avoids the use of environmentally detrimental components such as carbon disulfide and halogenated solvents. The melting temperature of the syndiotactic 1,2-polybutadiene can be varied from about 100 to about 190 ° C. by variations in the catalyst components and the component ratios. The ability to vary the melting temperature with a single catalyst composition is very desirable. The syndiotactic 1,2-polybutadiene can be used as a plastic or as an additive for rubber compositions wherein it can crosslink with conventional rubbers using conventional crosslinking agents.

  • Patent number: 6255520
    Abstract: The invention relates to a process for the preparation of an organic solution of dialkyl peroxydicarbonate which is particularly suited for use in the aqueous suspension polymerization of halogenated monomers. According to this process, the dialkyl peroxydicarbonate, prepared by the reaction in water of appropriate amounts of alkyl haloformate with an inorganic peroxide, is separated by extraction by means of a water-insoluble organic solvent chosen from conventional chain-regulating agents for halogenated polymers.
